Per "objdump -x src/pl/plpython/plpython3.dll | less -pOrdinal/Name", those symbols aren't exported. The Cygwin toolchain appears to export every function until you mark one with __declspec (dllexport), after which it exports just the ones so marked. Since plpython3.dll has an explicit __declspec on PyInit_plpy(), that's the sole function exported. Adding -Wl,--export-all-symbols to the PL/Python link lets the build complete; I have not researched whether it is a proper fix. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
